ROBERT O. BODMAN, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO MERGENTH'ALER LINOTYPE COMPANY, `.ACORPORATJ-ION OF NEW YORK.

- LINE-CASTING MACHINE.

T0 all 'whom it may concern.

Be it known that I, ROBERT O. BOARDMAN, of Grand Rapids, county ofJent, and State of Michigan, have invented a new and usetul Improvement in Line-Gasting Machines, of which the following is a specification.

My invention relates to line casting machines of the Mergehtlialer class and similar machines, in which circulating matrices repstored in a channeled magazine and released therefrom hy escapeiiientdevices controlled by finger keys or otherwise.

The invention is applicable more especially to machines in which several superimposed magazines are employed, each containing a font or series of matrices, but may be vemployed in machines having single magazines. 1

The invention consists in an escapement device movable'laterally in relation'to the matrices, and in cooperating matrices loiigi tiidinally grooved or recessed for a portion of theirlength, so thatl after an escapement has heen moved laterally to release a matrix it may be returned into the groove in the side of the outgoing matrix, to a position in which it will becertain to engage and arrest a succeeding matrix.

Referring to the drawings Figure 1 is a vertical cross section through the forward end of'a ser-ies of magazines and my escapewitli the adjacent parts. Fig. 2 is a pei'- spective view illustrating one of the escapements and the matrix, showing the manner. in which the escapement holds the matrix in its normal position. Fig. 3 is a siiiiiflarv view showing the"`manner in which. the'je's# capenient entersthe'ehannel or recess in-the outgoing matrix. Fig. 4 is a front'elevationof a series of escapements and 'their .actuating devices. i A

Referring to theffldrawing hA,gAfi ue tlc.- representa serieslof ii'clinedmagazinesleo'n'- sisting of parallel'l fo :ved plates, adapted to 'e'cive 'fand g'u`ide' the edges of the matrices'Bfaslu'siial .in lVlergenthaler machines, and- "-familiar to those skilled in the art.

.in action. This plate is provided with a horizontal slot or openingi, which may be brought opposite any one of the magazines to permit the escape of the matrices therefrom, as shown in Fig. 1.

D represents the matrix controlling cscapenient, which consists of a vertical 1elastic arm mounted at its upper end so :is to bend laterally, and having at the lower end a lateral lip d, which overlaps the forward end of the foremost matrix iii order to prevent its escape from the magazine. The release of a matrix is effected by moving the escapement laterally, as shown in dotted' matrix. y

In order that the second matrix may he" arrested with certainty, and prevented from` escaping, each matrix is provided with a3"r longitudinal recess or channel b, as shown', in Figs. l and 8, this recess extending from the upper or rear end ofthe matrix t0 a point near the forward end,'which.is preferably left of full thickness. lVhen the matrix is thus constructed the escapement may be lines in Fig. 4, until it diseiigages from the '.10

permitted to return to its normal position very quickly, and while the matrix is pass-v ing it, for the reason that the lip will in such case enterthe recess Z), as shown `in Fig. 3, without retarding the first matrix.

The advantage lies in the fact that single 'escapem'entmember ,will i'eleaseftlie'" ment mechanism adjacent thereto, together forei'iiostvniatrix. and arrest the second-one with.certainty. The invention .in this regar onsists, broadly, in the employment of a laterally movable escapeinent with a iiia-' ti'ix recessed fora portion et itslelngt-h only.

Thelescapements may be inovecl'"la'teiallv bv- 'ock'lshaft E, mounted in the s" and at the front ,end withv crank ai'iis -lltgwillbe'observed that the foremost. 'IH'TT' eesproject, atne corner beyond the' -iiiagazi-nes, and through the opening in the plate'-'Cgso that they 'iii-ust he returned or- 'lviusliedfbackwartl intothe iiigazines beto purpose. To this end I mount them at the upper" end on horizontal pivots d-, so' that their lower ends may be swung rearward, as indicated in dotted'lnes, to push the matrices inward. For the purpose of thus movingthe escapements I employ a horizontally movable bar d2, through which their lower ends extend, this bar being guided in the frameand operated by an angular hand lever gF, the movement of which effects the backward movement of all the matrices; and the matrices thus returned to the magaP zine may be locked therein by the insertion of a transverse bar in a manner well understood, or by any other suitable means. -When the lockingbar is removed, the downward movement of the matrices serves to re'- .A store. the escapements D to their normal or operative position. -This fea-ture in itself constitutes no part of my invention, as if .desired this return movement of the bar d might be effected bysprings or connections to a hand lever" (not shown).

' Having described my invention, what I claim 1s:

1. The combina-tion with a. matrix having abody portion and ears projecting therefrom, of an escapemcnt comprising a nger arranged to engage transversely with the said body portion between the ears and hold the matrix, and movable at right angles to the plane vof the matrix to release it.

2. `.In a machine of the class described, an escapement consistin of a single finger formed on one side'with a lip to engage the of thematrix, said lip adapted to enter theI recess named after the matrix has advanced from its normal position, whereby the escapement is permitted to lreturn to a position for engaging an second matrix While the first `matrix 1s 'passing 1t.

4. In a machine 'of the class described, escapements having lateral 'lips in combination with the-matrices having the longitudinal channel or depression b in^their sides to receive lthe escapement lips and permit the passage of the matrices thereby.

5. In a machine of the class described, the.

combination 'of a maga-zine, the 4matrices therein, and the escapements movable in one path to control the discharge of the matrices and also movable in another path to restore Aprotruding matrices to the magazine.

In testimny whereof I hereunto set my hand this 13th day of November, 1911, in the presence of two attesting Witnesses.
